Novel insights into Hodgkin lymphoma biology by single cell analysis.

about cell-to-cell interactions at single cell resolution. Applied to lymphoma, recent advances in single cell RNA sequencing have broadened opportunities to delineate previously underappreciated heterogeneity of malignant cell differentiation states and presumed cell of origin, and to describe the composition and cellular subsets in the ecosystem of the tumor microenvironment (TME). Clinical deployment of an expanding armamentarium of immunotherapy options that rely on targets and immune cell interactions in the TME, emphasizes the requirement for a deeper understanding of immune biology in lymphoma. In particular, classic Hodgkin lymphoma (CHL) can serve as a study paradigm due to its unique TME, featuring infrequent tumor cells among numerous non-malignant immune cells with significant inter- and intra-patient variability. Synergistic to advances in single cell sequencing, multiplexed imaging techniques have added a new dimension to describing cellular crosstalk in various lymphoma entities. Here, we comprehensively review recent progress utilizing novel single cell technologies with an emphasis on TME biology of CHL as an application field. The described technologies, that are applicable to peripheral blood, fresh tissues and formalin-fixed samples, hold the promise to accelerate biomarker discovery for novel immunotherapeutic approaches, and to serve as future assay platforms for biomarker-informed treatment selection including immunotherapies.

Overexpression of the key metabolic protein CPT1A defines mantle cell lymphoma patients with poor response to standard high dose chemotherapy independent of MIPI and complement established high-risk factors.

In addition to deregulated proliferation, we show that thermogenesis, fatty acid degradation and oxidative phosphorylation are altered in patients with poor survival, and that high expression of carnitine palmitoyltransferase 1A (CPT1A), an enzyme involved in fatty acid degradation, can specifically identify high-risk patients independent of the established high-risk factors. We suggest that complementary investigations of metabolism may increase the accuracy of patient stratification and that immunohistochemistry-based assessment of CPT1A can contribute to defining high-risk MCL.

PCSK9 antibodies target a serine protease (PCSK9), which promotes the degradation of the LDL-C receptor impacting on LDL-C plasma levels and (ox)LDL-C-receptor-mediated signaling in platelets similar to but more potent than statins. These functionally synergistic actions are the basis for numerous interactions between antiplatelet and these lipid-lowering drugs, which may, in summary, reduce the incidence of atherothrombotic vascular events.

Increased Cancer Risk in Patients with Kidney Disease and Venous Thromboembolism: A Population-Based Cohort Study.

During subsequent years of follow-up, the SIRs declined to 1.5 (95% CI: 1.3-1.6) when compared with the general population, and 1.1 (95% CI: 0.9-1.2) compared with VTE patients without kidney disease. Patients with hospital-diagnosed kidney disease have increased cancer risk after VTE, especially within the first year following the VTE diagnosis.

SARS-CoV-2 vaccination: Long-Term Follow-up of Pre-Existing and De Novo Immune Thrombocytopenia (ITP).

Among 11 patients who received rescue treatment, 7 had pre-existing, difficult-to-control ITP; exacerbations in these 7 may not have been caused by the vaccine. Six separate patients with de novo ITP post-SARS-CoV-2 vaccine who were followed for a median of 11 months (range 3-15) responded well to standard treatments for ITP and had favorable longer-term outcomes.

Survival Implications of Thrombus Recurrence or Bleeding in Cancer Patients Receiving Anticoagulation for Venous Thromboembolism Treatment.

Among cancer patients receiving anticoagulant therapy for VTE, adverse outcomes such as VTE recurrence, major bleeding, or CRNMB increase mortality risk by 40 to 80%. Identifying variables predicting these outcomes may help risk-stratify patients with poor prognosis.

Biosimilars in rare diseases - a focus on paroxysmal nocturnal hemoglobinuria.

As prescription drug spending has increased and exclusivity periods have expired, manufacturers have developed biosimilars-biologics that may be more affordable and highly similar to a licensed biological therapeutic, with no clinically meaningful differences in safety or efficacy. With biosimilars gaining regulatory approval around the globe and broadening patient access to biologics, this review aims to help rare disease healthcare providers familiarize themselves with biosimilars, understand their development and regulatory approval process, and address practical considerations that may facilitate their use.

A novel tRNA-derived fragment tRF-3022b modulates cell apoptosis and M2 macrophage polarization via binding to cytokines in colorectal cancer.

Mechanistically, we found that tRF-3022b binds to galectin 1 (LGALS1) and macrophage migration inhibitory factor (MIF) in CRC cells and reduces polarization by regulating MIF in M2 macrophages. In conclusion, our study revealed the expression pattern of tRFs in both tissue and plasma exosomes and identified a novel tRF, tRF-3022b, which may affect CRC tumor growth and M2 macrophage polarization by binding to LGALS1 and MIF.
